Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed April 13, 1905. Serial No. 255,344.

To all whom t may concern:

Be it known thatI, WARREN H. TAYLOR, of Stamford, in the county of Fairfield and State 'of Connecticut, have invented certain new and useful Improvements in Means for Attaching Dial-Locks to Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved diallock. In locks of this class where the lock is secured to the inner face of the door and the dial to the outside it frequently happens, owing to the unequal thickness of the door to which the lock is attached or to carelessness in attaching the parts, the relation between the dial and the tumblers is changed or altered, so that the parts bind or do not work properly.

The object of this invention is to provide a constructionof parts that will allow'for such irregularities within all reasonable limits and still preserve the proper relation of the working parts of the lock; and it consists in the parts and combination of parts, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure l is a View of the face of the lock, showing the opening. for the passage of the dial-spindle. Fig. 2 is a view, partly in elevation and partly in section, showing the dial secured to the lock. Fig. 3 is a view in elevation ofthe rear face of the dial-ring, and Fig. 4L is a plan view showing the means for locking the screw to the hub.

l represents a combination-lock of any approved form and construction provided in its face, that rests against the door, with an opening 2 for the passage of the dial-spindle 3. Integral with this lock-casing and surrounding the opening 2 is a nose or projection 4, having diametrically located mortises 5, the said mortises communicating with the spindle-opening 2. This nosing 4 is cylindrical in shape and is designed to project into an opening formed in the door and extends only partly through said door.

6 is the dial-ring provided on its outerrface with an upturned edge adapted to receive the edge of the dial 7 and provided on'its inner face with a sleeve or part having tenons 8, which latter are adapted to rest in the mortises 5 in the nosing l and hold the dialring 6 and the lock in their proper relative positions and permit of the connection of the parts irrespective of the thickness of the door within, of course, the limits of adjustment of the two parts and irrespective of any irregularities of in the thickness of the door. After the parts have been thus placed and connected they are secured together by screws 9, passing through holes 6 in the dial-ring 6 and into threaded holes 6b in the nosing 4: on the lock-case. With this arrangement the dial-ring 6 can readily be placed in its proper lposition with relation to the tumblers and held there irrespective of the thickness of the door within all reasonable limits.

The ordinary manner of constructing similar locks is to make the nose of the lock-case lof suicient length to extend through the a device the length of the nose must bear a' fixed relation to the thickness of the door, whereas with my invention in a lock of the size shown the thickness of the doors may vary to the extent of a quarter of an inch without any alterations in Athe lock par'ts. It is of course apparent that the extent of the possible variations may be increased or diminished without departing from the invention.

After thelock-case 1 has been secured to the door and the dial-ring 6 secured to the lock, as explained, the tumbler-carrying gear lO is placed in position in the lock-case, with its threaded hub ll in line with the spindle-opening in the nose of the case. The threaded spindle 8, which is fast to the dial 7, is then passed through the dial-ring 6, door, and nose 4, and into thethreaded hub l1 and is secured to the latter by rotating the dial. This turning movement of the spindle 3 in the femalethreaded hub 11 draws the dial 7 up to the dial-ring 6, and the parts are then secured by drivingakey or wedge 13 into grooves formed in the adjacent faces of the spindle 3 and hub ll, the location of these grooves controllingv the relative position of the dial and tumblers. After the parts have been thus assembled the tumblers are placed in position and the lock closed by the cap-plate 15. The advantages IOO IOS

llock-case are obvious, and there is the further advantage that if the metal door is not of uniform thickness or if the hole for the nosing is not bored exactly straight the working parts will nevertheless come in proper alinement, by reason of the fact that the screws 9 fasten the dial-ring 6 directly to the lock-case 1. Hence the relation between these two parts is always the same.

It is evident that many slight changes might be made in the relative arrangement of parts herein shown and described without departing from the spirit and scope of 'my invention. Hence I would have it understood that I do not wish to coniine myself to the exact construction of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a dial-lock, the combination with a lock-case having a nose provided with mortises, of a dial-ring having a part provided with tenons to enter said mortises, and screws passing through the ring and into the nose for locking the parts together.

2. In a dial-lock, the combination with a lock-case having a nose provided with mortises therein, and a central opening for the dial-spindle, of a dial-ringhaving a part provided with tenons to enter the mortises in the nose, screws passing through the dial-ring and engaging the nose, and a dial and dial-spindle,

the latter passing through the ring and nose and connected with the mechanism of the lock.

3. In a dial-lock, the combination with a lock-case having a mortised nose, and. a turnbler-carrying gear having a threaded hub, of a dial-ring having a part provided with tenons adapted to enter the mortises in the nose, screws passing through the ring and into threaded holes in the nose, a dial, and a screwthreaded spindle fixed to the dial and passing through the ring and nose and engaging the threaded hub of the tumbler-carrying gear.

4. Inadial-lock the combination with alockcase having a mortised nose, and a tumblercarrying gear having a threaded hub the latter having a key-groove therein, of a dialring havinga part provided with tenons adapted to enter the mortises in the nose, screws passing through the ring and into threaded holes in the nose, a dial, a screw-threaded spindle fixed to the dial and passing through the ring and nose and engaging the threaded hub of the tumbler-carrying' gear, the said screw having a groove therein, and a key or wedge driven into the grooves in the hub and spindle, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

WARREN H. TAYLOR.
